We've lived with human error for 100+ years in this game and we can keep on living with it.

I'm in the camp that wants to see the correct call every single time, if possible. In the early 1900s they had no choice but to live with human error--nowadays the technology to move away from that is all there, we just choose not to use it. For instance--we see the pitch tracker after every single pitch and can immediatly tell whether it was a ball or strike.

Personally I think the botched call that cost Detroit a perfect game a few years back was the beginning of a movement that will eventually result in a dramatic shift as to how games are officiated. If a missed call ever dramatically impacts a World Series, things will get very interesting.
